My math sucks. 50% of 195 is 97.5. 40% of 205 is 82. Definitely lower profile. > I am referring to the 5-spoke Enkei's on the '97 STO (Miata.net has > them listed at 14.5-lbs...) Those aren't the wheels that most people are thinking of when you mention 5-spoke 15" miata alloys. The wheels that you have are semi-rare. Except for the special editions, Mazda did not start using 15 inch wheels until 1999. I had a set of the same Enkei wheels, they also came standard on the 1996 "M" edition, but those were the only two cars that Mazda put them on, less than 8,000 sets of that style of wheel total. They are still one of my favorite looking factory miata wheels. Much better looking than that nasty looking lightweight set they put on the '93LE and the '95M. ;-) Pat (running for cover) |

you better run! talkin' trash 'bout my 92SE wheels too there texas boy ;-)
Hey, the 99 I just bought has these great looking 17"wheels, they're by TSW and I was hoping that they would be light or semi light, I was wrong. In comparison, I've weighed a wheel and tire combo on the 14"BBS forged wheels (that Pat is talking trash about) at about 25lbs, a 14" steel wheel and tire combo at about 35lbs and.........drum roll please..........one of my new 17" TSW wheels with tire at 40 stinkin' pounds! I'm hoping to get a chance to transfer the set and be able to drive the 99 with the BBS to see the actual handling difference. That should be interesting! Weights above are not precise or directly comparable as all three tires are different sizes and brands.

It was just typical that the 1996 "M" edition that I bought had wheels that I liked the looks of a bit better than the BBS wheels on the "M" of the year before, but they weighed something like 4 additional pounds each, the heaviest alloy wheel released on a miata at that point. > Hey, the 99 I just bought has these great looking 17"wheels, they're by TSW > and I was hoping that they would be light or semi light, I was wrong.

I still have the stock 15" alloys with the EVS-100's because I haven't made a final decision on selling them yet. (may go back to a more stock miata). I think that they are about 30 pounds, 13.2 pounds for the wheel. We could put those on your miata and you would have an idea of how the car is stock, except for the much better tires, of course. I don't think that I have seen a 1999+ with the BBS wheels on it. You might like how they look on there and going from 40 to 25 pounds per wheel/tire will make a huge difference. You also shouldn't have any problem selling the TSW's if you decide to replace them. Pat |

My '96 came with Borbet wheels and tires that say "Ecasta Supra 205/50R15
86V" on them. I've got the stock wheels on now because the above didn't seem ideal (to say the least) for winter driving. I don't know squat about *wheels/tires... can anyone comment on these? miker *except that every car I've had with alloys has had rim leaks and has needed at least one bent wheel replaced. No problem with steelies here! |

How many alloys is that total? Sounds like bad luck. I have been driving for 21 years now and have lost track of how many different sets of alloy wheels I have bought, used, sold, etc., but it is a lot. Most of these have been factory. I currently have two sets of 5-spoke 15" miata wheels, as well as a set of SSR comps that I have been driving on for about 12,000 miles. None of these are bent, and none have rim leaks. I drove the '96M with 3 different sets of wheels on it for over 5 years and never had a rim leak or wheel bend. That is now over 6 years and over 85,000 miles without a rim leak or a wheel bend using four different sets of alloys, just counting miatas. In 21 years I remember two rim leaks and I have never bent a wheel, though I have scraped a curb or three. I also never had a bent wheel on any car that I have bought. Again, sounds like I have either had really good luck or vice-versa with you. No problem with steelies here! The problem is that they weigh 18 pounds, which is apparently what Mazda uses as their maximum wheel weight before performance really suffers. Less wheel weight is always good. The car will drive fine with steelies, but it will drive better with alloy wheels that weight less, assuming that they are not bent and are holding air. ;-) Pat |

I drove a 96M for 6 years and had to have 2 of the four wheels repaired. The first time, I remember the bump that bent the wheel, and it had to be fixed immediately (the tire would no longer seal). The second time I don't know when it got bent -- I just noticed that the steering wheel was vibrating, and the next time I had tires mounted they mechanic showed me that the wheel was noticably out of round. > In 21 years I remember two rim leaks and I have never bent a > wheel, though I have scraped a curb or three.

I've had to buy three (all on different cars); I've had at least one rim leak on *every* alloy car, probably 8-9 vehicles. My last, a '94 Acura Legend, had intermittant rim leaks on three of the four rims. Maybe this is Minnesota? > No problem with steelies here! > > The problem is that they weigh 18 pounds I understand the difference between sprung/unsprung weight for handling, but so far as acceleration and speed I think the difference between me and a 100-lb 20-something lead-footed babe is going to make more difference than that few pounds of wheels. miker |

Some have estimated the effect of unsprung mass on acceleration at 10X that of sprung mass. Do you weigh >380 pounds? :-) [here's the math: 10 x 4(18-11) + 100] My tires lose about one psi per week. It was the same with the stock wheels, so I assume that's normal for alloys. My Honda's steel wheels might lose one psi per year. -- Lanny Chambers '94C, St. Louis http://www.hummingbirds.net/alignment.html |
